STOVE.

SPECIFIGATION forming part of Letters Patent No. 766,217, dated August 2, 1904.

Application filed December '7, 1903. Serial No. 184,100. No models To all whom it may concern:

Be it known that I, \VILLIAM H. CALKINS, a citizen of the United States, residing at O0- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Stoves, of which the following is a specification.

My invention relates to the improvement of heating-stoves, and has particular relation to that class of stoves known as gas-stoves.

The objects of my invention are to provide an improved construction of stove of this class wherein are combined improved means for generating and radiating heat from a suitable burner, to so construct my improved stove as to insure the utilization of a comparatively large per cent. of the heat generated at the burner, and to produce other improvements the details of construction of which will be more fully pointed out hereininafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which Figure 1 is a view in elevation of my improved stove. Fig. 2 is a plan view. Fig. 3 a vertical section taken on varying planes as indicated by the dotted line :1 :11 of Fig. 2, and Fig. i is a transverse section on line 1 ;1 of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ an upright main casing or drum portion 1, within the lower portion of which is adapted to be supported a suitable gas-burner 2, the burner shown being in the nature of a ringburner having upper side perforations and being supplied with gas through the medium of a gas-pipe 3. The form of the burner, however, is immaterial, and, as is obvious, fuel other than gas may be used in the lower portion of the stove. The pipe 3 may be provided with a suitable form of air and gas mixer, (not herein shown.) and air is further supplied to the interior of the casing 1 through the central opening 4 in the lower end of the casing. IVithin the casing l and arranged about the central portion thereof are a plurality of vertical pipes 5, these pipes connect- 1ngopposing openings 5" 1n the upper and lower sides of said casing and being arranged, as shown, on the outer side of the burner 2. Rising from the central portion and upper side of the casing in a smaller supplemental casing 6 and into the upper portion of the casing 6 lead the upper inturned end portions of vertical pipes 7, which extend downward on the outer side of said casing 6 and communicate with openings in the upper side of the casing 1, the connections of said last-mentioned casing and the lower ends of the pipes 7 being preferably effected between the openings 5. Leading downward through the otherwise closed upper end of the casing 6 is a central vertically-arranged pipe 8, the upper end of the latter projecting above the casingtop 6, from which it is suspended, and the lower open end of said pipe 8 terminating, as shown in Fig. 3 of the drawings, a short distance above the top of the casing 1. \Vith the upper end of the pipe 8 is adapted to be connected a suitable smoke or discharge pipe. (Not herein shown.) In its lower portion the casing 1 is provided with a doorway which is adapted to be closed by a suitable hinged door 9, and said casing 1 is provided with suitable supporting-legs 10.

In operation it will be understood that the combined heat and products of combustion which rise from the flame at the burner 2 or from other fuel used in the base portion of the stove-casing will pass through said casing I and pipes 7 into the upper portion of the casing 6 and thence downward, as indicated by the black arrows, to the lower end of the easing 6 and upward and outward through the pipe 8. This circulation of the heat and products of combustion within the casings and pipes 7 results in not only heating the surfaces of both the upper and lower casings and said pipes 7, and thereby heating a comparatively large radiating-surface, but will also result, through the circulation about the pipes 5, in heating the latter and in causinga comparatively rapid passage of air through said pipes 5, which is discharged into the room wherein the stove is located in a heated condition.

From the construction and operation described it will be understood that a comparatively simple stove construction is provided,

and leading vertically therethrough, of a supplemental casing 6 mounted on said casing 1, a plurality of pipes 7 connecting the upper portion of said casing 6 with the upper end of the casing 1 and a pipe 8 leading through and depending from the upper end of the casing 6, said pipe terminating at a point above the top of the casing 1.
